Description

technical field [0001] The invention belongs to the technical field of antibacterial material preparation, and in particular relates to an antibacterial, mildew-proof and deodorizing nanocomposite particle, a preparation method and application thereof. Background technique [0002] It is well known that ZnO nanoparticles are an inorganic metal oxide with antibacterial activity. As an ultraviolet photocatalyst, zinc oxide usually realizes antibacterial function under the excitation of ultraviolet light. However, ZnO can still exhibit significant antibacterial properties in the absence of light. [0003] Recent studies have shown that the antibacterial activity of ZnO mainly originates from surface oxygen vacancy defects. Oxygen vacancy defects can activate oxygen molecules in the air after capturing electrons to generate reactive oxygen species with strong oxidative capacity. The active oxygen species can in turn kill various microorganisms and degrade volatile organic gas...
